Aurinia Pharmaceuticals Inc. is a commercial-stage biotechnology company specializing in therapies for autoimmune diseases, with a primary focus on lupus nephritis. The company leverages its proprietary product LUPKYNIS and its collaboration and license agreement with Otsuka Pharmaceutical Co. Ltd. Aurinia Pharmaceuticals Inc. focuses on developing and commercializing therapies to treat diseases with unmet medical need.
Tang’s large acquisition of Aurinia Pharmaceuticals stock occurred less than a week before the company reported positive news for its lead drug, Lupkynis. A new long-term analysis of a phase 3 trial supporting the Food and Drug Administration’s approval of Lupkynis shows that it lowered the risk of kidney-related events or death in patients with lupus nephritis by more than half.
Patients randomized to receive Lupkynis were 78% less likely to exhibit increasing levels of protein fragments in their urine, a signal of kidney damage.
Lupkynis sales got off to a slow start when the drug was first approved to treat lupus nephritis in 2021. Total sales surged 24% year over year to an annualized $310 million in the first quarter of 2026. With recently announced long-term results that show the sort of benefits that get the attention of physicians and their patients, sales of the treatment could rise past $1 billion annually in a few short years.
Aurinia is already profitable. First-quarter net income jumped 48% year over year to an annualized $137.6 million. With profits on the rise, following the CEO’s lead and increasing your Aurinia position seems like a smart move.
